DARPA’s INSPIRED program is pushing quantum photonics into the battlespace, promising ultra-sensitive squeezed light detectors that could redefine sensing, stealth, and surveillance.

Introduction: From Physics Breakthrough to Battlefield Advantage The next decisive military advantage may not come from faster missiles or larger platforms—but from the ability to detect what was previously invisible. At the frontier of this shift lies a radical transformation in sensing: the manipulation of light at the quantum level. For decades, all optical sensing…
